Sarah St. Lifer, Associate Editor, StyleList, and mother

The best advice my mother gave me was to moisturize my neck. When I was younger she would point to women with plastic surgery and note that although they had "perfect" faces, their necks would give away their actual age. I moisturize with Elizabeth Arden's 8 Hour Cream before I go to bed -- my mother swears by it, and now I do too.
